Plutonium-240 decays according to the function Q(t)=Q 0 e^ -kt where Q represents the quantity remaining after t years and k is the decay constant 0.00011 ... To the nearest 10 years , how long will it take 36 grams of plutonium-240 to decay to 12 grams?
9,990 years
How long would it take a radioactive isotope to decay if it has a half life of 10 years?
It will take 8 days. The half life is the time it takes half of an element to decay.
How long it would take for 99.9 percent of Cs to decay if its half-life is 30 years?
10 half-lives or 300 years.
How many grams of a 35 gram sample of radium will decay in 5000 years if the half-life of radium is 1602 years?
approx. 31 g.
How long does it take a 200 gram sample of carbon-14 to decay to a mass of 100 grams?
About 5700 years. The half-life of carbon-14 is 5700 years, and the question is asking how long for 200 grams to become 100 grams. That is half, so the answer is 5700 years. It will take another 5700 years for the mass to further decay to 50 grams, and another 5700 years to decay to 25 grams.
What is the exponential formula for population growth?
exponential decay formula is y=A x Bx
When was exponential growth and decay invented?
They were not invented because they predated the first human beings. They existed at least millions of years before there was anyone to "invent" them.All novae produce radioactive elements and these decay exponentially. So exponential decay predates the formation of the solar system.I am not sure, but stellar fusion may be exponential. But, in any case, there are life forms on earth, like bacteria, that exhibit exponential growth. These bacteria, and therefore exponential growth, predate human beings by a few million years.They were not invented because they predated the first human beings.

How is the half-life of a radioactive isotope found?
The half life of actinium (for the natural isotope 227Ac) is 21,773 years.
The half life of Radium-226 is 1600 years How many grams will remain from 5 grams after 365 years?
The amount of material left in radioactive decay is an exponential function. Therefore, the way you solve this is to write it as an exponential function; for example: f = e-kt, where "f" is the fraction remaining after a certain time, "t" is the time in any unit you choose (for example, years), and "k" is a constant you have to find out. Replace the numbers you know (for t = 1600 years, f = 1/2, since 1/2 of the original remains), and solve for "k". Then, write the equation again, this time with the constant "k" you figured out before, and the time (365 years). This will give you the fraction left after that amount of time.
When was The Years of Decay created?
The Years of Decay was created on 1989-10-13.

When did the human populationm experience exponential growth?
300 years ago
What is the possible origin of graphite?
Graphite, coal and diamonds are all thought to be products of the decay and compression of vegetable matter from millions of years ago. Diamonds progress from coal.
What is the half life of the penny?
Back about thirty years ago, I took a huge container full of pennies and, with nothing better to do, sorted them by year and stacked them. I found that, yes, the distribution is a pure exponential decay, for a good thirty or forty years. I determined that the size of a year's stack 7 years back from a later stack is about half the size. Thus, the half life of a penny is 7 years.
What term used to describe rate of radioactive isotopes?
Half-life (in units of time).Half-Life is the rate of radioactive decay, measured in time. The half life gives the time it take for half of the radioactive atoms in a system to decay. Fore example, if you have 10 grams of carbon-14, it will take 5730 years for half of it to decay, giving you 5 grams. In another 5730 years, you'll have 2.5 grams left, etc...Isotopes decay at an exponential rate. A half-life is the time that half of the population of an isotope will decay. The measure is a statistical probability and is more accurate when a large population is observed. The term half-life is applied to describe a property of a given isotope (i.e. the half-life of Carbon 14 is 5730).half life
